  • GHSA-8v63-cqqc-6r2cPrototype Pollution in object-path2021-09-20ghsa · osvUS

    object-path is vulnerable to Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution'). The `del()` function fails to validate which Object properties it deletes. This allows attackers to modify the prototype of Object, causing the modification of default properties like `toString` on all objects.
